- Using datagrams in Java
- The User Datagram Protocol UDP allows an application to send data in packets with a low overhead and is employed in some important standards, like DNS and RADIUS. Many programmers may not be familiar with the protocol, though, since it is harder to program and less frequently used than TCP....

- Check the efficiency of Oracle's caching with this report
- One of the most important areas of Oracle tuning is the management of the RAM data buffers. Oracle performance will be dramatically improved if you can avoid a physical disk I/O by storing a data block inside the RAM memory of the data buffer caches. Historically, an Oracle professional would...

- Tweak Oracle data buffer parameters to cache entire databases
- In this advanced Oracle article, I will explore the internal mechanisms of the Oracle data buffers, the RAM that Oracle uses to prevent unnecessary rereads of data blocks from disk. Understanding how Oracle’s data buffers operate is an important key to successfully using them in performance tuning a database.Prior to...

- A new view in Oracle9i helps determine data buffer size
- The data buffers feature enhances database performance. But how do you know what buffer size to use? Oracle9i solves this problem with a new view.The ability to compute the optimal size of the data buffers is a critical task for large databases. As databases grow to hundreds of billions of...

- Creating tablespaces with multiple block sizes
- Optimizing database I/O is a DBA's most important performance tuning activity. Follow these steps to maximize Oracle9i database performance through the use of multiple block sizes.Oracle9i supports multiple data buffer sizes, which you can use to segment and partition disk I/O patterns within the database. Oracle9i also allows segregated RAM...

- Buffer Overflows for Beginners
- So what is a buffer overrun and why should you care? The SANS institute a few months back released a list of the 10 most commonly used methods to break into servers. Of these ten a large number can be attributed to buffer overrun vulnerabilities. They are a major problem....

- An Efficient Buffer Management in a Network Interface Card
- This paper proposes a dynamic packet buffer management algorithm for a protocol processor in a network terminal. The protocol processor is to handle high-speed data streams, more than 10 Gb/s, in a Network Interface Card NIC. There are two types of packet buffer management algorithms, static and dynamic. In general,...

- Windows NT4 Security Patch: Index Server Search Function Contains Unchecked Buffer (exe)
- Microsoft has released a patch that fixes a vulnerability in Index Server 2.0 which has an unchecked buffer in a function that processes search requests. If an overly long value were provided for a particular search parameter, it would overrun the buffer. If the buffer were overrun with random data,...

- Long Distance Replication Technologies: Volume-Based Asynchronous Replication Buffering Advantages
- A long-standing, popular alternative technique to achieve long-distance, remote replication is known as asynchronous data replication. Asynchronous data replication's advantage unobtrusively provides long-distance, remote data replication, thereby preserving application performance as it provides disaster recovery data protection. One asynchronous data replication factor of particular importance is the often-overlooked asynchronous replication...

- Packet Buffer Management for a High-Speed Network Interface Card
- Packet buffers in a smart network interface card are managed in a way to reduce any packet losses from high-speed burst incoming data. Currently, two types of packet buffer management techniques are used. They are static buffer management and dynamic buffer management techniques. Dynamic buffer management techniques are more efficient...
